The New Scooby-Doo Movies is an American animated mystery comedy television series produced by Hanna-Barbera for CBS. It is the second television series in the Scooby-Doo franchise, and follows the first incarnation, Scooby-Doo, Where Are You! It premiered on September 9, 1972, and ended on October 27, 1973, running for two seasons on CBS as the only hour-long Scooby-Doo series. Twenty-four episodes were produced, sixteen for the 1972–73 season and eight more for the 1973–74 season.

Aside from doubling the length of each episode, The New Scooby-Doo Movies differed from its predecessor in the addition of a rotating special guest star slot; each episode featured real world celebrities or well-known animated characters joining the Mystery, Inc. gang in solving mysteries. This concept was later revisited with a similar animated series titled Scooby-Doo and Guess Who?, which premiered in 2019.

The New Scooby-Doo Movies was the last incarnation of Scooby-Doo airing on CBS, and also the franchise's final time to feature Nicole Jaffe as the regular voice of Velma Dinkley, due to her marriage and retirement from acting.
